The Gas XRSC Series is ATM Innovation’s most affordable "street/strip" race carb yet. It has all the features of high-end race carburetors – based on quality ATM die cast aluminum main bodies, metering blocks and throttle-bodies. This cost savings over billet components doesn’t hamper performance, and you still get ATM's all aluminum dual inlet, dual site-window fuel bowls, changeable idle and high-speed air bleeds and changeable idle feed and power valve channel restrictions providing endless tuning capabilities. The throttle-bodies have vacuum tubes for vacuum advance and PVC hookups. These carburetors are precisely calibrated at the factory and are “race-ready” out of the box requiring minor “trim” adjustments for atmospheric conditions and your individual race combination. They are available in 650, 750, 850, 950 and 1050 CFM sizes for 4150-style flange manifolds.
